• I’ve been thinking about upgrading one of my reps, mainly the crystal and maybe swapping the movement for something smoother. The thing is, I’m not sure if it’s worth spending another $200–300 on a piece that already cost me less than $600. Part of me loves the idea of getting it as close as possible to the real thing, but another part says it’s just not practical. Has anyone here gone through with upgrades like that? Did it actually make a big difference in how it feels or performs?
